Question

The formula for converting from Celsius to Fahrenheit temperatures is F=9/5C+32

Answer 1

Both the original and the inverse are functions because for each value of C there is a unique value of F and vice-versa.

i.e.
B. Original is a function; inverse is a function

Answer 2

Answer:

The correct option is B.

Step-by-step explanation:

The formula for converting from Celsius to Fahrenheit temperatures is

$F=\frac{9}{5}C+32$

A relation is called a function if there exist a unique output for each input.

The original formula is a  function because for each value of C, there exist a unique value of F.

The inverse of the function is

$F-32=\frac{9}{5}C$

$\frac{5}{9}\times (F-32)=C$

The inverse is also a function because for each value of F, there exist a unique value of C.

Therefore original is a function; inverse is a function. Option B is correct.
